Innovations and Design

Driving system performance through innovationZehnder ventilation systems innovative technology make for less complexity, increased heat recovery efficiency, lower specific fan power and significant noise reduction.

A perfect combination of outstanding technical performance and excellent features makes ComfoAir Q the best in class achieving top efficiency ratings.

Unique, ultra-powerful heat exchanger – for maximum energy efficiencyTheuniquediamondheatexchangerfeatures

an especially large surface, which allows it to

achieveahigherlevelofefficiency.Variable

lower pressure loss. As a result, less energy is

required to overcome the air resistance.

State-of-the-art fan technology – for quiet, energy-saving operationTheflowgrid,scrollhousingandimpeller

guaranteesnotonlyextremelyquietoperation,

but also particularly low power consumption.

A high-quality, future-proof solution, based on

tried-and-tested technology.

Intelligent temperature control of the intake air – for the best possible energy efficiency The pre-heater adapts its operation taking

intoconsiderationtemperature,airflowand

humidity to ensure consistent supply air

temperature is achieved no matter what is

going on outside. Thanks to its large surface

and delta shape, the level of pressure loss

is negligible – and that also reduces the

power consumption.

Innovative air volume balancing – for maximum heat recoveryNew and patented: innovative sensor technology

because there is no need to adjust the speed manually and

the air volumes are balanced automatically.

Heat recovery performance Noise reduction

Heat Recovery Performance is an important factor in unit specification as it has a direct impact on the heating load and offers savings to the homeowner.

When comparing two MVHR units with 87% and 94% heat recovery efficiency you can achieve up to a 25% reduction in heating costs (from ventilation loss) if selecting the higher performing unit.

Did you know that for every increase of 3dB (A) the sound you hear is doubled?

ComfoAir Q’s sound performance of 28*dB(A) means one competitor unit is equivalent to 8 ComfoAir Q units in operational noise!

*28 dB(A) @ 3m achieved for ComfoAir Q450 up to 315 m3/hat50Pa6 7

Air Distribution

Perfect integrationWith a full range of components designed to work together, Zehnder ComfoAir Q can be integrated into a home simply and effectively to provide fresh air and comfort.

How it works

Easier, more efficient and more comfortable

1. Supply of fresh air:

Fresh air is fed into the system

viaanexternalwallvent.The

fresh outside air can optionally

flowthroughasub-soilheat

exchangerbeforehandwhich

uses geothermal energy to

pre-temper the outside air.

2. Ventilation unit:

Up to 96% of the heat is

recoveredfromtheextract

air and transferred to the

fresh air. This can be

humidified,dehumidified,

heated and cooled using

optional components.

3. Air distribution:

The air distribution system

channels fresh air at the right

temperature to individual

rooms as needed and vents the

extractairtotheoutside.The

air volume can be individually

adjusted for each room.
